Statistics

Explanation

Total file open requests

The total number of scan requests from the filer that were accepted for scanning by Sophos Anti-Virus for NetApp Storage systems (this number will not increase if a request can not be satisfied because of some internal problem – see “Requests denied”)

Requests denied

The number of times a request from the filer was denied by the Sophos Anti-Virus for NetApp server. This increases every time Sophos Anti-Virus for NetApp Storage systems service (savnaser.exe) cannot obtain internal resources (e.g. no free synchronisation semaphores, creating threads failed, etc. If it increases steadily, it means that the Sophos Anti-Virus for NetApp server is running out of internal resources.

File open failures

Increments when attempts are made to access a viral file on the filer, or access to the file that needs scanning was denied by OS for some other reason

Current thread count

The current number of threads in use for scanning files on the filer, as one thread is used per file this is effectively the number of files currently being scanned

Highest thread count

The highest number of files that have been scanned at any one time

Average round-trip time

This is calculated by dividing elapsed time by number of total file open requests

Effective round-trip time

This is is calculated by taking the number of scans per minute, divided by 60 and multiply it by 1000. This gives the result in milliseconds

Scans per minute

The number of files scanned per minute of elapsed time

Elapsed time

The elapsed time since the Sophos Anti-Virus for NetApp service started

Statistics

Explanation

Total file open requests

The total number of scan requests from filers that were accepted for scanning by Sophos Anti-Virus for NetApp Storage systems (this number will not increase if a request can not be satisfied because of some internal problem – see “Requests denied”)

Requests denied

The number of times requests from filers were denied by the Sophos Anti-Virus for NetApp server. This increases every time Sophos Anti-Virus for NetApp Storage systems service (savnaser.exe) cannot obtain internal resources (e.g. no free synchronisation semaphores, creating threads failed, etc. If it increases steadily, it means that the Sophos Anti-Virus for NetApp server is running out of internal resources.

Current thread count

The current number of threads in use for scanning files on filers, as one thread is used per file this is effectively the number of files currently being scanned

Highest thread count

The highest number of files that have been scanned at any one time

Average scan time (ms)

This is calculated by dividing "Total file open requests" with a counter, which counts the total time spent with scanning

Elapsed time

The elapsed time since the Sophos Anti-Virus for NetApp service started
